problems with data logging

I'm having problems getting the data logging feature working correctly. The only way I can get it to work at all is using the GUI timer. If use any other timers it doesn't record. Also I need to record at around 1 data point a second and no matter what I set the GUI timer to it records around 12 data points per second. Can anyone help me out?

I figured it out. Everything works correctly in Windows 7 64 bit except the timers. I set it up again on a XP laptop and the timers worked correctly. It also worked in 32 bit Windows 7 using the logic timer.
